我将以下页面片段和表单配置为允许用户将照片上传到他们的个人资料。当用户更新他的个人资料但未指定图像时，上传的原始图像将从个人资料扩展字段中删除。它回到空白。

问题：有没有办法防止这种情况发生。希望允许用户更新个人资料，但不删除之前上传的图像 URL。

不记得确切的 formIt 是如何工作的，但请尝试从此处的值占位符中删除fi.前缀：

<div class="input"><input id="nomination_file" name="nomination_file" type="file" value="[[+nomination_file]]" maxlength="100000" /></div>

这样，输入应该填充现有的图像路径，如果没有上传另一个图像，则将重新提交。
